What Alaska LNG becoming a federal project means
Updated October 21, 2026 · Numbers as published by each source on the date shown
Alaska LNG has been selected for the federal U.S. Investment Accelerator program, its developer Glenfarne says, and the investment structure is now being worked out. That could include a federal ownership stake, while the state keeps its 25%. South Korea and Taiwan are reviewing investments but have not finalized them, and the final investment decision to build has not been made.
What the project is
Alaska LNG would carry natural gas from Alaska's North Slope through an 807-mile, 42-inch pipeline, with a North Slope gas treatment plant and an export terminal in Nikiski that could ship 20 million tonnes of liquefied natural gas a year, according to Glenfarne. Glenfarne says the project could cost up to $55 billion.
It is planned in two phases. Phase One is the pipeline, which would deliver gas to Alaskans first. The project's October 1, 2026 report to the Department of Energy puts the main Phase One line at about 739 miles, with mechanical completion targeted for 2028 and first gas in 2029. Phase Two adds the export terminal, gas treatment plant and compressor stations.
What "federal project" means so far
Glenfarne's head of Alaska legal and corporate affairs, Becky Windt Pearson, said the administration selected Alaska LNG for the Investment Accelerator, a program created last year and overseen by the Department of Commerce. The next steps are to finalize the investment structure with the government and close the transaction, she said. The open questions include what stake, if any, the federal government takes.
People familiar with the effort told the Anchorage Daily News that Glenfarne's 75% ownership could be reduced or eliminated, with the company staying on as developer. The Department of Commerce did not respond to the newspaper's questions.
Who might pay
- South Korea. A $50 billion-plus South Korean investment was announced on September 30, 2026. Korean officials say the pipeline is not yet confirmed as part of their US investment deal, and its inclusion depends on further talks and a review of the project's economics.
- Taiwan. Taiwan's economic affairs ministry said it will invest up to $4.4 billion and is preparing to buy as much as 30% of the gas. Specific arrangements, equity stakes and terms will be set in later negotiations.
- Commercial agreements. Glenfarne's agreements now cover 13 million tonnes a year of the 16 million Glenfarne is targeting before a final investment decision.
What stays the same: the state's 25% stake
Frank Richards, head of the Alaska Gasline Development Corp., said the state will keep its 25% equity stake. Its key federal approvals have held up in court. The Federal Energy Regulatory Commission authorized the project in 2020, and on April 15, 2025 a federal appeals court denied challenges to the Energy Department's export orders.
Steps left before construction
- Investment structure. Agree on who owns what, including any federal stake, and close the transaction.
- Final investment decision. This is the formal go-ahead to build. It was first proposed for 2025 and has not yet been made.
- Long-term contracts. The project has not yet signed long-term export or supply contracts, its October 2026 filing says.
- Property taxes. Under the current ownership, Glenfarne says it still needs a state property tax change to lower costs in the early years, before full operation.

What it could mean for Alaskans' gas supply
Phase One is built to deliver North Slope gas to Alaskans first, before exports begin. Glenfarne says the property tax change matters for that phase, because the current tax structure would push gas prices for Alaska users too high before the project is fully running.
Common questions
What does it mean that Alaska LNG is a federal project?
Glenfarne says the project was selected for the federal U.S. Investment Accelerator program, which is run by the Department of Commerce. The company says it is now working with the government to finalize the investment structure, including what stake, if any, the federal government takes.
Will the federal government own part of Alaska LNG?
That is still being negotiated. People familiar with the effort told the Anchorage Daily News that a federal ownership stake is possible. The state's Alaska Gasline Development Corp. says it will keep its 25% stake.
Is Taiwan investing in the Alaska gas pipeline?
Taiwan's economic affairs ministry said on October 14, 2026 that it will invest up to $4.4 billion and is preparing to buy as much as 30% of the project's gas. It said the investment arrangements, equity stakes and terms will be set in later negotiations.
